Corrinne and Arthur Cantrill have been key Australian experimental filmakers for the last 50 years but, as is so often the case with avant garde film soundtracks, Arthur's sonic assemblies have not so far been collected and considered as listening objects in their own right, so this release is timely. Using tape machines and musique concrete techniques, Cantrill works mostly with raw environmental sounds, treated but not disassembled, layered with processed instrumental sounds. Not hi-fi and not aestheticised, these are strong and irreducible sonic objects. The four minute Petunias is a particularly unusual experiment in pure panning. A specialised but interesting release. With notes by Warren Burt and Arthur Cantrill.L
